Isoprenoid biosynthesis was investigated in the two diatoms Phaeodactylum tricornutum and Nitzschia ovalis by labeling experiments performed in mixotrophic growth conditions with sodium [1-(13)C]acetate, 13CO2, [1-(13)C]glucose, sodium [3-(13)C]pyruvate and 1-deoxy-D-[5,5-(2)H2]xylulose. A clear dichotomy was found. Acetate was the preferred carbon source for the formation of the sterols in the cytoplasm via the mevalonate pathway. Carbon dioxide was the main source for phytol biosynthesis in… CONTINUE READING
